Feeling depressed about the conflation of fiction and fact in the first few months of 2017, I steered a car into the hills of Calabasas to meet with one person whom many rely on to set things straight. This is an area near Los Angeles best known for its production of Kardashians, but there were no McMansions on the street where I was headed, only old, gnarled trees and a few modest houses. I spotted the one I was looking foróa ramshackle bungalowóbecause the car in the driveway gave it away. Its license plate read SNOPES.
